Hi, First it depends if you want to do kernel or userspace tracing? For userspace, lttng-ust requires dynamic linking, so that's a no go. On the kernel side, you will need to either build lttng-modules in your kernel image or ship the modules in your initrd. Then you'll have to statically build lttng-tools and all it's dependencies. I see no obvious reasons why it wouldn't work, but it's not a scenario we do any testing for.
